After the screw is removed, the directional signal housing must be moved directly forward without any upward or lateral angulation, expecially the latter. Just slide it forward alongside the headlight housing. Once it's glided horizontally forward a bit less than one inch, it's off. It took a bit of pressure to get the housing moving, at which point I broke off the top tab while not elevating it to clear the headlight housing. The front turn signal #7440 bulb is clear in my '99LS.

I neglected mentioning that, after removing the bulb from my right front directional signal module, the appearance of the bulb filiment looked OK. I reinserted the original bulb into its female socket finding the bulb to function, as it continues to do so 3 days after the removal. Only thing noted on the bulb was some slight discoloration of its two outside wire contacts that I suppose represents corrosion? How long does your bulb stay functioning after a bang on the lens cover? I would not think that the bulb, as designed, would malfunction by being loosened without completely falling out of its socket. Take a look at a 7440 bulb seeing what I mean. Also not mentioned is that I broke off the retaining tab held by top screw when removing the unit (I failed to elevate the tab so that it would clear the edge of the headlight module). Small bits of good old duct tape refastened the tab so that all fits tightly together again.

I found that the plastic module on my '99 LS400, containing the front #7440 turn signal bulb, may easily be moved. First remove the small phillips screw holding the tab at the top of the module. Next raise the loosened tab and slide the entire unit directly forward. The module is held in place by a plastic tab attaching it to the lateral side of the headlight module and two other tabs in its rear that fit into small fender/body holes. The unit reattaches easier than its removal. Incidentally, for this fix, the $10 look at the '99 LS400 shop manual pages on http://techinfo.lexus.com/ was a useless experience.

My right front turn signal bulb has failed. I wonder if you ever found how to change your left front turn signal bulb. I, too, question if the main front light assembly must be removed in order to access the bulb in question.
